I am writing a project in MVC . I have an Admin section wherby initially all the data is entered .
I have a table called STUDENTS fields STUDENT_ID (Primary Key and auto generated number) and field STUDENT_NAME .
I have a controller , model and view . I can add entries to this table but how can I make it error if same name is entered again - .
I'm using SqlMembershipProvider and SqlRoleProvider for user management.
Users are created by
Dim MCS As System.Web.Security.MembershipCreateStatus
Dim NewUser
As MembershipUser = Membership.CreateUser(TB_UserName.Text, TB_Pw.Text, TB_Email.Text, TB_SecQuestion.Text, TB_SecAnswer.Text,
False, MCS)
later, after email confirmation, I take the user into a specified role
Dim myUser As System.Web.Security.MembershipUser = Nothing
myUser = Membership.GetUser(New Guid(Request("RegID")))Catch
If myUser
IsNot
Nothing
Then
myUser.Comment += " approved "
Membership.UpdateUser(myUser)
Roles.AddUserToRole(myUser.UserName, "role")
End if
After this I have two entries with the same UserName in aspnet_Users table, but with different UserId's. One UserId is referenced in aspnet_Membership table and the other in the aspnet_UsersInRoles table.
We have developed the Application using Visual Studio 2008, After publish we got the issue like After Submitting the Form the user can able to Move Backward and do the Refresh. This will again triggers the Submit Post Back and the Duplicate Record Created As Well.
This is happening for all the Web Forms. How to Avoid this ? I need a Generic Solution where i can implement that logic in Base Page then the rest of the Pages this functionality will be covered by default.
Moreover, Before Refresh We should also intimate user "Do you Want to Post the Same Data Again ?", if the user clicks Yes then it can allow the same record can be posted again.
How to do this ?? But i cannot disable the Browser Features like back, forward and Others. I have found many solutions in various web sites but it is also happening for the Validation Part Also...
I am using the built in database with the tables (i.e. membership, users, etc...). I created my own table (relationships), but when I try to create a row that uses the same email address it says "cannot create duplicate entries". I am not allowing duplicate email addresses in the membership table. That did not work because I couldn't convert System.Guid to long. So, I decided to do it by email address. I changed idRequester to requesteremail and the same for receiver. However, when I try another record with the same email address in either field, it does not accept it.

How do you avoid duplicate bound items in this scenario: There's a databound control on a page (a DropDownList in this case, though I don't think it matters). It has AppendDataBoundItems set to "true". Somewhere in the code, a DataSource is set and DataBind is called. So this control is bound explicitly. You have a bunch of other things to bind on the page, so you call Page.DataBind.
Your databound control now has duplicate items in it. It was (1) bound explicitly, then (2) Page.DataBind bound it again. Since AppendDataBoundItems was true, the second bind appends to the first, and you end up with double the items. A couple limitations: The explicit call to DataBind on the control is done through some centralized code, and would be painful to change. i really need to bind the rest of the page in aggregate (via Page.Databind()) because there's too many other databound elements to do it individually without writing a ton of individual calls.
I need a method like... Page.DataBindExceptIfTheyHaveAlreadyBeenBoundDuh()
I have a receipt page for my clients that will display their info and they will get notify by an email message. Here is the problem: when user hit refresh button from a brownser, it will send duplicate email message to the user.
This is what i have:
protected
void Page_Load(object sender,
EventArgs e)
{ if(!IsPostBack)
SendEmail()
}
protected void SendEmail()
{ //here is my function for email
}
I have 3 textboxes and one submit button outside gridview. This textboxes submit value to gridview.
I want to be able to check and stop duplicate value in gridview.
I need to force every request to https://www.mysite.com (always with https and www)
The site is hosted in GoDaddy and I need to do it via IIS7 URL Rewrite Module.
I've been able to do the HTTPS redirect with the following code:
<system.webServer>
<rewrite>
<rules>
<rule name="Canonical Host Name" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^mysite.com$" />
</conditions>
<action type="Redirect" url="https://www.mysite.com/{R:1}" redirectType="Permanent" />
</rule>
</rules>
</rewrite>
</system.webServer>
Test cases
http://mysite.com -> https://www.mysite.com OK
http://www.mysite.com -> https://www.mysite.com NOT WORKING
I guess the condition is not being satisfied when I enter www.mysite.com in the browser, so there's no redirect and the page serves as HTTP instead of HTTPS.
I think I just need to modify the condition pattern, but I have almost nothing regex knowledge and I need this asap.
After postback if user presses F5 or refresh duplicate values are inserted.

An option to add a range of computers based on tag numbers, for instance, user input 800101 and 800110 would add computers SYS800101, SYS800102, SYS800103, SYS 800104, SYS800105, SYS800106, SYS800107, SYS800108, SYS800109, and SYS800110. Currently the app adds a single computer at a time.
